Kaplan-Meier survival curves according to immunohistochemistry (IHC) scores for negligible and weak cyclooxygenase-2 (COX-2) expression (IHC scores 0–4) versus moderate and strong COX-2 expression (IHC scores 5–12) (p = 0.023; A), and the individual stratified categories (p = 0.002; B), analyzed using the log-rank test.
